Subtract one outfielder from the battle for an A’s roster spot next season.

Chris Snelling was claimed on waivers by the Tampa Bay Devil Rays on Thursday, ending an injury-plagued stint in Oakland that saw the Australian play in just six games.

The A’s acquired Snelling from the Washington Nationals for outfielder Ryan Langerhans on May 2. He hit .350 in six starts but was lost to a season-ending left knee injury May 11 while running out a grounder.

Snelling had been a player the A’s long coveted despite his history with left knee problems. He participated in the team’s instructional league earlier this month but was limited in his drills.

“Unfortunately, the situation was a health issue with Chris,” A’s assistant general manager David Forst said. “We traded for him and liked his talent. (But) we weren’t sure what his health was going to be going into spring training.”

Snelling is the third player the A’s have lost on a waiver claim this offseason, along with lefty reliever Jay Marshall and outfielder Kevin Thompson.

The A’s are trying to clear space on their 40-man roster to provide some flexibility for other moves this offseason. Reliever Connor Robertson cleared waivers and was outrighted to Triple-A Sacramento.

Also Thursday, the A’s filled the last opening on their coaching staff by promoting Triple-A manager Tony DeFrancesco to be the new third base coach, replacing Rene Lachemann.
